The 1! <br />unit is positioned vertically on the <br />bottom of the tank annulus or at <br />maximum fuel level of a tankto preven[ <br />overflow. The all-polysulfone level <br />switch features a single -pole, single - <br />throw contact, actuated by the float of <br />the unit.

Ut Listed 4880 <br />Madel LS -7 Tank Level Sensor <br />The Model LS -7 Level Switch is designed for <br />horizontal applications where access is difficult, such as <br />a dual -wall fiberglass tank's annulus. The unit is eni6- <br />neered to provide high -reliability point -level sensing. <br />The plastic construction is compatible with all hydrocar- <br />bon liquids, providing long, trouble-free performance. <br />Listed 48RO <br />11111.1 IUIII iYr�i' <br />Intrinsically Safe <br />Power Supply <br />Sensor Alarm <br />Modules <br />tntr4rsk2lly <br />Safe Barriers <br />Field wiring <br />Compartment <br />Power Input <br />Terminals <br />ModelSLS-3 N.O. &LS -30 <br />Hydrostatic LeakDetectors <br />The Models LS -3 N.O. s —' <br />and LS -30 Leak Detectors <br />monitor any U.L. ratedi°`"�fi t ' : •i• , <br />hydrostatic double-wall <br />fiberglass tank reservoir. <br />Due to the possibility of <br />groundwater seeping into a <br />reservoir, the LS 30 is de- <br />signed to detect liquid level <br />gains as well as losses. <br />LS -10 and LS 20 <br />Reservoir Assemblies are0 <br />supplied when a permanent Ti.ervoir is not part of [he j <br />tank package.

The Model IT -21P Positive Pressure Leak <br />Sensor is designed to provide monitoring of the <br />annular cavity of double-wall tanks via air <br />pressure. Any breach of the containment will <br />cause a pressure loss and will be <br />sensed by the pressure switch trans- <br />figuring its contact should pressure fall <br />�below .5 PSIG. <br />.9✓7 The Model IT -2V vacuum Leak <br />Sensor monitors for loss of vacuum <br />and will be sensed by the vacuum switch trans- <br />ferring Its contact should vacuum fall to .5 inches <br />of mercury. <br />W <br />1— <br />
